How can plaster be removed from the back of interior ceramic tiles so they can be used again? These are tiles from 1952 and are needed for repair on a bathroom wall over a sink.

Try the easiest way first. Soak the tiles overnight in a bucket of water. Then use a scraper, like a 5 way tool to get the plaster off. If it wont come off then the same scraper tapped with a hammer will apply more force than just hand scraping. If that doesnt do it, the next step would be to use a power tool. The best would be a right angle grinder with a diamond tipped turbo blade. Tilt the grinder so the flat edge of the blade drags across the plaster. The tile should be stabilized so the spinning action of the blade doesnt send it flying off. Do this outside as the dust will be unreal. A belt sander with rough sand paper may also work but will take a lot longer as you will be changing the paper frequently.

The ultimate would be a diamond cup wheel on a grinder but I dont expect you to know what that is and they are expensive, about $75 for a 4" wheel. If these tile are part of an elaborate resetting it may pay to investigate the cup wheel routine. I can get you the names of some online stores that sell the wheels. The 4.5" right angle grinder can be had at HD, Lowes or Sears for under $80.
